GRILLE FOB HEATING FL'UES.

Application filed March 3, 1924.

This invention relates to new and useful improvements in grilles forheating flues.

In certain types of heating devices, such as is shown for instance, inco-pending application Serial No. 657,337, filed August 14, 1923, andpatented May 27, 1924, Number 1,495,262, warm air is discharged fromseparate fines and it is desirable to keep the air currents dischargingfrom one flue separate from those discharging from the other fine, butto discharge them at the same location...

The object of my invention is to provide a grille adapted to set into awall surface and equipped with relatively concentric coupling members,whereby fines, one within the other may be connected with the grille.

A further object is to provide means for ornamenting and concealing theends of the fines and for breaking up the air currents into numerousstreams, whereby a better distribution is had.

A construction designed to carry out the invention will be hereinafterdescribed together with other features of the invention.

The invention will be more readily understood from a reading of thefollowing specification and by reference to the accompanying drawings,in which an example of the invention is shown, and wherein:

Fig. 1 is a front elevation of a grille constructed in accordance withmy invention,

Fig. is a side elevation of the same,

Fig. 3 is a vertical sectional View on the line 33 of 1, and a Fig. f isa cross-sectional view on the line ll of Fig. 1.

In the drawings the numeral 10 designates a flat rectangular frame whichis preferably imperforate, except for fastenings. An outwardly bowedforaininous panel 11 is formed within the frame.

Along the line of intersection between the Serial No. 696,658.

frame and the panel is provided a laterally projecting collar 12,extending at right angles to the frame. The panel is shown formed of aplurality of intersecting rightangular bars and a rectangular mullion 13is worked into this design and may have a slight projection as is shownin Figs. 2, 3 and 4. The mullion is formed inte ral with a laterallyprojecting collar 1%, which is thus supp rtcd by the panel. The de..ignof the panel is not essential.

V1 hile the collar 14; is relatively concentric within the collar 12, itis shown as spaced further from the top than it is from the bo tom onthe theory that a greater volume of hot air would pass out of the upperportion of the grille. The outer collar 12 is fitted within the end of alaterally extending flue 12, while the collar 14- enters a laterallyextending flue 14 within the fine 12.

The hot air currents passing through the two fines are separated andenter the respective collars. 'lhe grille covers the ends of the finesand provides an ornamental cover. The collars may also be used tosupport the fines in position.

Variouschanges in the size and shape of the different parts, as well asmodifications and alterations may be made within the scope of theappended claim.

What I claim, is:

An integral flue grille comprising a marginal frame having a foraminouspanel and a collar passing through and beyond the op posite faces of thepanel and spaced on all sides from the frame to leave a greater space atone end than at its sides and opposite end, said panel being bowedoutwardly from the sides of the frame to said collar to position thelatter forward of the frame.

In testimony whereof I aflx my signature.

THEODORE A. SALA.
